Hello, I'm fairly new to audio on linux, so please be patient... I try to use GWC to clean recordings from cassette tape and LP's (both 33 and 78 rpm). The idea is use gwc as an alternative to Cool Edit Pro. But as my pc is set up with Alsa I have to use the oss emulation layer, or record in another application. But here comes the problem. I record with Ardour (this seem to work the best at this moment). Then I cut the recording and export the pieces as .wav (or some other format). This is where the problem starts. I tried exporting as .wav with float/32bit/24bit/16bit samples. Only with 16bit samples can I open the file [b] and play [/b]. The other sample formats give a "soundfile format not allowed" error, but as far as I can see, the file is completely read. Only the sound is not played back. The cursor moves, but nothing comes out the speakers. I get the same with .au and .raw formats. Using gwc 0.20-7, libsndfile 1.0.9 and fftw 3.0.1. If more info needed, just ask. I'm not that knowledgable that I know what to include. Anyone an idea how I can verify if the files are really bad (the equivalent of an exifreader)? Anyone an idea of a recording application (using alsa or jack) that can output .wav files in float/32bit or 24bit that gwc can 100% import? Thanks in advance, Johan De Groote |

Johan, This almost certainly means that the headers on the wavefiles created with Ardour are malformed. It is libsndfile that reports the error, and GWC relays it to you in a human readable form. jw Johan De Groote wrote: >Hello, > >I'm fairly new to audio on linux, so please be patient... > >I try to use GWC to clean recordings from cassette tape and LP's (both 33 and >78 rpm).
